Do different buffs stack? Can one use the exp buff and the battle speed buff at the same time and get boosts from both?

Yup

Sweet. lvl100 now possible in 4-5 hours of training :)

if you buy stars on the bot then it probably is, the buffs would add up quickly for a low level bot w/o many trophies.

naw its more for the ones who lead a clan and buy stars that will get the most, especially if its a top 25 clan and you get in HoF for monthly energy and overall energy. theres many way to do all this.

Yeah it really speeds up training. Ive managed to get from lv 82-97 today in 7 hours so I reckon that lv 100 in 24 hours would be possible.

yea and the lower lvls go way faster. i barely have int on my lvl 50 bot and it went from 50 to 60 in less than 20 mins

I've done lvl100 in 35 hours on this bot when the game launched. That includes lvl1 to lvl60 on cellphone while at work so was 15 lvls behind the leader when I finally got to my PC. Also, take away 6 hours of sleep and time to cook/eat etc.. this bot made it to lvl100 in less than 24 hours playtime.

So with the new buffs it can be done 2.5x2.5=6.25 times faster. That's around 4-5 hours. It only takes about 4000 to 5000 trains to get to lvl100 if done efficiently so that costs (125+125)x5=1250 achievement points for the best leveling buffs. It should be easy enough to accumulate that amount on the way up. (I've trained a few bots to lvl100+ and have gotten over 1000 points on each of them without even trying to get points. Still can get a lot more on them if needed)

Wont be any excuse for all the low levels thenn..

Sure there is, camping sucks and I'll stay under lvl 70 so I never have to camp anything harder than a venom grip.
